FOREWORD:

• This Operation and Maintenance Manual was written to give the owner/operator instructions on safe operation and maintenance of the Bobcat loader.
• READ AND UNDERSTAND THIS OPERATION AND MAINTENANCE MANUAL BEFORE OPERATING YOUR LOADER. If you have any questions, see your Bobcat Loader dealer.

SAFETY INSTRUCTIONS:

A. SAFETY IS YOUR RESPONSIBILITY:

• The Skid Steer Loader is a highly maneuverable and compact machine. In operation, it is rugged and useful under a wide variety of conditions. This presents an operator with hazards which are common for off highway, rough terrain applications but are not unique for use of Bobcat loaders.
• The loader has an internal combustion engine with resultant heat and exhaust. All exhaust gases can kill so the loader must be used with adequate ventilation. The loader must not be used in an area with explosive dusts or gases or so that the engine exhaust can contact flammable material.
• The loader has a spark arrestor muffler which is required for operation in certain areas. For loader applications, the dealer recommends the capabilities and restrictions of the loader and attachments for each application. The dealer demonstrates the safe operation of the loader according to the manufacturer's instructional materials which are also available to all operators. The dealer can also identify unsafe modifications or use of unapproved attachments.
• The attachments and buckets are designed for rated capacity and secure fastening to the loader. For each model loader, the user must check with the dealer or manufacturer's literature to identify each bucket or attachment for safe loads of materials of specified densities.

The following publications provide information on the safe use of the loader and attachments: 1. The Delivery Report is used to check whether complete instructions have been given to the new owner.2. The Operator's Manual delivered with every loader gives operating information as well as routine maintenance and service.3. Every loader has machine signs (or decals) which instruct on the safe care and operation of the loader. The complete signs and their location are shown in the Operator's Manual. All signs are available from your Bobcat dealer.4. The loader has a plastic Operator Handbook fastened to the operator cab. It has brief operating instructions always available to the operator. The handbook is available from your Bobcat dealer in an English Edition or a combination English, French, German, Spanish edition.5. The Service Manual and Parts Book are optional manuals from your Bobcat dealer for use by mechanics to do shop-type service and repair work.
